By default, the holding disk area is 100% reserved for incrementals.  To 
use it and its highly recommended to save shoe-shining wear and tear on 
the drive, you should change the keyword Reserved in your amanda.conf to 
allow it to be used for fulls too.  I use 30% here.

This 'holding disk' is a buffer area/directory on one of your hard drives 
that is used as a scratchpad area, where files being compressed are built 
up until that particular disklist entry is completed, at which point it 
is all written to the tape at the tape drives (or the interfaces) full 
speed.  Without such a holding disk area setup and in use, any backup 
that involves compression will be written as the compressor spits it out, 
so the drive will be stopped and started many times, trying to recue back 
to where it wrote the last data each time.  This wastes considerable time 
and multiplies the wear on the drive by quite a bit.
